The 3.5-liter V6 Toyota 2GR-FXE engine was produced at the concern’s plant from 2009 to 2020 and was installed in hybrid versions of the Crown Majesta, Highlander, as well as the Lexus GS and RX. There are two versions of the unit: with distributed or combined fuel injection.
In 2009, the first version of this hybrid engine appeared on the Lexus RX450h crossover. By design, this is a conventional V6 engine with an aluminum block and a 60° cylinder camber angle, distributed fuel injection, a pair of DOHC heads with hydraulic lifters, a timing chain, VVTi phase shifters on all shafts and an ACIS variable geometry intake manifold. Since this is a hybrid engine, the system includes two electric motors and a small battery.
In 2012, the second version of this unit debuted on the Lexus GS 450h sports sedan, which featured D-4S combined fuel injection and a slightly higher compression ratio. Of the features, we note the operation of all modifications of the motor according to the Atkinson economical cycle.
The engine was installed on:
- Toyota Crown Majesta 6 (S210) in 2013 – 2018;
- Toyota Highlander 2 (XU40) in 2010 – 2013; Highlander 3 (XU50) in 2013 – 2016;
- Lexus GS450h 4 (L10) in 2012 – 2020;
- Lexus RX450h 3 (AL10) in 2009 – 2015.

Disadvantages of the 2GR-FXE engine
- Despite the fact that this is a rather late modification of the power unit of the 2GR line, scuffing in the fifth cylinder is as common here as in its predecessors. The reason is considered to be overheating due to a defect in the design of the engine cooling system.
- Another well-known problem of motors in this series is the crackling of the phase regulators, and many owners of such motors have spent a lot of effort and money to get rid of it. Someone is helped by replacing only the sprockets, but often you have to buy new couplings.
- The weak points of this power unit also include a short-lived water pump, ignition coils and fuel-sensitive AFS sensors and lambda probes. Quite a few complaints are related to lubricant leaks and especially on the timing cover.
